To all whom 'it may concern.'

Be it known that I, FRANK SLOGR, a c1t1 zen of the United States of America, residing at Omaha, in` the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Roller Skates, of which the following is a specification.

This invention relates'to certalnnew and useful improvements 1n roller skates and has .particular reference to a skate ofthe twov `same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed. In the drawing, wherein likereference characters designate corresponding parts throughout the several views, l j

Figure 1 is a side elevational view ofa roller skate constructed inI accordance with the resent invention,

Figure 2 is a top plan view of the same, Figure 3 is a vertical cross-sectional view taken'on line III--III of Fig. 1,

Figure 4 is a verticall cross-sectional view taken on line IV-IV of Fig. 1,

Figure 5 isa perspective view of one of the bracket mountings for the wheel or roller, f l

Figure 6 is a developed plan view of the bracket, and f Figure 7 shows edge elevational view of the form of bracket shown in Fig. 6.

The roller skate embodies a frame structure having sole and heel plates 1 and 2 respectively connected together by cooperating adjustable extensions 3, the sole plate 1 carrying the usual sole engaging screw adjustable clamps 4 while the heel plate 2 carries the heel engaging flange 5 to which heel straps may be attached in the usual manner.

Single rollers Gare positioned beneath the sole and heel plates 1 and 2 respectively l the mounting or bearing for each roller 6 embodying a pair of resilient brackets depending from the sole and heel plates to support the roller in the absence of the usual nuts and screws. The manner of constructingl one ofthe brackets for supporting a roller is disclosed in Figs. 6 and 7, the arm 7 carrying a mountin plate 8 at one end thereof, that is adapte to be angularly bent as shown in Fig. 5 and provided with a series of openings 8 to accommodate rivet;

ing the bracket arm 7 as at 9 to the sole and heel plates 1 and 2. The lowerdepending end of the bracket arm 7 carries a vcross head 10 substantially rectangular in plan view with a grooved or ribbed portion 11 extending longitudinally'of the cross head 10 while diametrically opposite corners of the cross heads carr relatively long finger extensions 12 and 3 disposed at opposite sides of the groove 11. The lower end of the arm 7 adjacent the cross head 10 is provided with an opening 14 for purposes presently to appear.

The arm 7 is bent upon a transverse line slightly below the opening 14 in a direction opposite the bracket mounting 8 and the cross head 10 is then bent into circular formation to form an annular groove or chanthe finger 12 overlapping'the opposite side of the cross head 10. while the finger 13 is positioned between the grooves 11 and the bracket arm 7.

The roller 6 includes a supporting frame -15 having a central tubular web or bearing 16 that encloses a shaft 17 having flanges 18 upon opposite ends thereof. The flanges 18 are received in the annular grooves 11' and the free ends of the circular portions of the cross head engage the shaft inwardly of the flanges and abut the opposite ends of the wheel bearing 16 as shown in Fig. 4. The split bearings for the ends of the shaft 17 are resilient so that the rollers may be mounted upon the bracket arms by forcibly separating or expanding the bearings at the lower ends of the bracket arms 7. It will 4be noted thatl the openings 14 appear at the outer sides of the bracket arms, and upon bending the cross head 10 into circular formation, the walls of the openings are slightly distorted to form a lip at the lower side of the openin forming a retaining w'all for a lubricant t at is introduced at the ends of the bearings for the roller.`

The cooperating bracket arms may be forcibly separated for removing a roller and shaft carrled thereby.

While there is herein shown and described the preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What is claimed as new is 1. In a roller skate, extensibly connected sole and heel plates, bracket arms depending from the plates, each arm` being struck from sheet metal and bent to provide a circular bearing at its lower end with an annular groove in the bearing and a shaft carrying a roller and having an annular flange at each end received in the bearing groove.

2. Ina roller skate, extensibly connected sole and heel plates, bracket arms depending from the plates, each arm being struck from sheet metal and bent to provide a circular bearing at its lower end' with an annular groove in the bearing, a shaft carrying a roller and'having an annular flange at each end received in the bearing groove, said bearing being bent from a rectangular plate with. the edges moved into abutting relation and tongue extensions carried by the meeting edges of the bearing and circularly inclosing the bearing.

3. In a roller skate, extensibly connected sole and heel plates, bracket arms depending from the plates, each arm being struck from sheet metal and bent to rovide a circular bearing at its lower en with an annular groove in the bearing,ashaft carrying a roller and having an annular flange at each end received in the bearing groove, and said bracket havin an o ening therein alined with the end o the s aft to facilitate lubrication of the bearing.

A 4. In a. roller skate, extensibly connected sole and heel plates, bracket arms depending from the plates, each arm bein struck from sheet metal and bent to provi e a circular bearing at its lower end with an annular groove in the bearing, a shaft carrying a roller and having an annular flange at each end received in the bearing groove, said bearing being bent from a rectangular plate with the edges moved into abutting relation, tongue extensions carried by the meeting edges of the "bearing and circularly inclosing the bearing, and said bracket having an opening therein alined with the end of the shaft to facilitate lubrication of the bearing.

5. In a roller skate, extensibly connected sole and heel plates, bracket arms depending from the plates, each arm being struck from sheet metal and bent to cular bearing at its lower en with an annular groove in the bearing, a shaft carrying a roller and having an annular flange at each end received in the bearing groove, said bracket having an opening therein alined with the end of the shaft to facilitate lubrication of the bearin 6. kIn a roller skate, extensibly vconnected sole and heel plates, bracket arms depending from the plates, each arm being struck from sheet metal and bent to provide a circular bearing at its lower end with an anlnular groove in the bearing, a shaft carry- .ing a roller and having an annular flange at rovide a cir- 'A each end received in the bearing groove,

said bearing being bent from a rectangular plate with the edges moved into abutting relation, tongue extensions carried by the meeting edges of the bearing and circularly inclosing the bearing, said bracket having an openlng therein alined with the end of Vthe shaft 'to facilitate lubrication of the bearin and an upturned lip at the lower side o the opening to retain the lubricant in the bearing.

In testimony whereof I allix my signature.
